I have done other juice cleanses and so far this has been my favourite. Typically I feel almost ill during the cleanse with a severe headache and sometimes dizziness. I chose the Immunity kit for 2 days and then added 6 additional juices of my choice for a third day. I made it through this cleanse overall without the terrible headache. I felt like I could have continued for another couple of days. My favourite juices were the very berry and the cashew (I added a little cinnamon to the cashew and it made it seem like dessert). :). After the cleanse my tummy felt much less bloated and I just felt generally healthier.
